WILLIAM ANDREW WOOD, OF NASHVILLE, TENNESSEE.

PLOW.

SPECIFICATION forming part of Letters Patent No. 609,602, dated August 23, 1898.

Application filed October 30,1897. $erial No. 656,905. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM ANDREW WOOD, acitizen of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented a new and useful Plow, of which the following is a specification.

This invention relates to plows of the subsoil variety and designed chiefly for ridging, turning stubble, and for general application, the parts being readily separable and adjust- 'able to adapt the implement to'the condition of the soil and the character of work to be performed.

For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.

The improvement is susceptible of various changes in the form, proportion, and the minor details of construction without departing from the principle or sacrificing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown inthe accompanying drawings, in which- Figure 1 is a perspective view of a plow constructed in accordance with this invention. Fig. 2 is a sectional elevation thereof. Fig. 3 is a rear view. Fig. 4 is a top plan view of the double moldboard. Fig. 5 is a top plan view of the subsoiler. Fig. 6 is a detail view in elevation of the lower portion of the standard. Fig. 7 is a sectional detail.

Corresponding and like parts are referred to in the following description and indicated in the several views of the drawings, by the same reference characters.

The beam 1 has a longitudinal slot 2 near its rear end, through which passes a rod 3, the upper end portion of which is threaded and receives a pair of clamp-nuts 41, disposed above and below the beam to clamp the latter and hold the rod 3 in an adj us ted position. The slot 2 admits of the upper portion of the rod 3 being moved forwardly or rearwardly, whereas the clamp-nuts provide for the vertical adjustment of the rod, so as to hold the furrow-bar 5 in the required position.

The standard 6 is offset intermediate of its ends, so as to throw its lower portion in vertical alinement with the center of the beam and its upper portion alongside of the beam,

against which it is clamped by a clip 7 in the ordinary. manner. The inner side' of the standard is roughened to make positive engagement with the side of the beam and prevent slipping after the clip has been properly tightened. The lower end of the standard is formed with afoot 8, which is pointed, and with an enlarged portion-9 immediately above the foot and overhanging the latter, whereby means is had for securing the subsoiler 10 in position without the use of bolts or like fastenings. The space formed betweenthe'foot 8 and enlarged portion 9 receives the subsoiler 10, which is supported upon the foot 8 and is retained in place by the overhanging portion of the part 9. A lug 11 is formed'with the foot 8 and is located centrally thereof and projects from its rear and has the furrowbar 5 pivoted at its front end thereto.

The furrow-bar 5 is curved longitudinally and has the lower end of the rod 3 pivotally connected thereto at its rear end and is recessed in its lower face to receive a wear-plate 12, held in position bya machine-screw 13 or other equivalent means. This wear-plate 12 may be of chilled iron or highly-tempered steel, or of any material desired, and is made detachable, so as to be replaced when worn or otherwise rendered unfit for further service. The subsoiler 10isatapering point of usual appearance and is formed with anopen slot 14, extending inwardly from its rear edge, so as. to receive that portion of the standard comprised between the parts 8 and 9, the latter overhanging the front and side portions bordering upon the said slot. A recess 15 is formed in the top side of the subsoiler to receive the lower edge of the moldboard, whereby a flush or snug joint is had, so that the earth will slide readily over the subsoiler and moldboard without interference, which would result if a projecting ridge or shoulder existed.

The moldboard 16 is double and is removably fitted to the standard and subsoiler and is supplied with a rearwardly-eXt-ending arm 17, which tapers slightly and has its upper and lower edges beveled to secure a dovetail joint with the standard, the latter being formed with a dovetail seat 18 in one side to receive the said arm 17. The forward edge v of the lower portion ofthe standard isoppositely beveled to con form to the angle formed between the wings of the moldboard, thereby admitting of the latter securing a 'neater fit and the standard presenting a better appearance.

WVhen assembling the parts, the double moldboard is first fitted to the standard, its arm 17 slipping into the seat 18, after which the subsoiler is placed in position by being slipped into the space formed between the moldboard and foot 8 until the shoulders formed by the depression 15 engage with the lower edges of the moldboard-wings, when the plow is in condition for use. A proper adjustment of the furrow-bar 5 is secured by manipulating the clamp-screws 4, the one being backed and the other turned up in the usual manner. By loosening the clip 7 the standard can be raised or lowered and moved forwardly or rearwardly to secure the required pitch to the subsoiler. A wedge 19, interposed between the top side of the beam and the upper member of the clip, facilitates the cantin g of the standard forwardly or rearwardly and is transversely corrugated to retain the clip in an adjusted position. This wedge rests loosely upon the beam and is prevented from moving rearwardly by means of a pin or stop 20, applied to the said beam and engaging with the rear edge of the Wedge.

Having thus described the invention, what is claimed as new is p 1. In combination, a standard havinga foot and an enlarged portion above and overhanging the foot, and a point having a slot extending inwardly from its rear edge to receive that portion of the standard extending between the foot and overhanging part, whereby the said poirfl; is retained in place, substantially as set fort v 2. In combination, a standard, a double moldboard detachably fitted to the standard, and a subsoiler removably fitted to the standard and havinga depression in its top side to receive the lower edges of the moldboardwings, substantially as and for the purpose set forth.

3. In combination, a standard bearing an earth-treating device and having a centrallydisposed lug at its rear edge, a furrow-bar pivoted at its front end to the said lug, and

"forth.

4:. In combination, a standard bearing an earth-treating device and provided with a centrally disposed and rearwardly extending lug, a curved furrow-bar pivoted to the said lug, a rod having pivotal connection with the furrow-bar, and means for adjusting the rod and holding it in an adj usted'position, substantially as set forth.

5. In combination, a beam having a longitudinal slot, a standard having adjustable connection with the beam and provided with an earth-treatin g device, a curved furrow-bar having pivotal connection with the standard, a. rod applied to the furrow-bar and having its upper end threaded and passing loosely through the longitudinal slot of the beam, and clamp-nuts placed-upon the threaded end portion ofthe rod to secure it to the beam in a desired position, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

WILLIAM ANDREW WOOD.
